This is meant for a course project to demonstrate how to construct plots that can be used for exploratory data analysis.
- README.md
- plot1.R - constructs a histogram showing the frequency of the variable Global Active Power in kilowatt.
- plot1.png - plot 1 saved to PNG file.
- plot2.R - constructs a line graph showing the variable Global Active Power in kilowatt and Date.
- plot2.png - plot 2 saved to PNG file.
- plot3.R - constructs a multivariate line graph showing the Sub_metering variables and Date.
- plot3.png - plot 3 saved to PNG file.
- plot4.R - constructs a panel with the graphs listed above plus a line graph showing Voltage and Date.
- plot4.png - plot 4 saved to PNG file.
- Visit the UC Irvine Machine Learning Repository Individual household electric power consumption data set to have a general understanding of the project and variables.
- Download and place the data in a ./data subdirectory.
- Run the scripts (plot1.R, plot2.R, plot3.R, plot4.R) to generate the graphs.
